Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, belong to the scope of protection of the invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in fig. 4. "front" refers to a direction close to the coupling end of the ferrule 11, and "rear" refers to a direction away from the coupling end of the ferrule 11.
The embodiment of the invention provides an assembly body for holding a ferrule, which comprises a first connecting sleeve 200 for holding the ferrule 11 and outer sleeves 410 respectively arranged at two sides of the first connecting sleeve 200; the outer sleeve 410 is capable of being connected to an external device to lock the assembly body by moving relative to the first connection sleeve 200 in a first direction; movement of the outer sleeve 410 relative to the first sleeve 200 in a direction opposite the first direction disengages the external device to unlock the fitting body.
The first connection sleeve 200 has a hollow structure with two open ends. As shown in fig. 2 and 8, the optical fiber 12 and the ferrule 11 constituting the ferrule assembly 10 are inserted into the first connection sleeve 200, and the end of the ferrule 11 can be exposed outside the first connection sleeve 200 for coupling connection. The outer jacket 200 need not be installed around the circumference of the first coupling sleeve 200, but only needs to be installed at both sides of the first coupling sleeve 200, and a partial region on the circumference of the first coupling sleeve 200 is not connected to the outer jacket 200, thereby reducing the size of the assembly body and further reducing the overall size of the connector.
Further, the first connection sleeve 200 includes a first sliding portion 220, the outer sleeve 410 includes a second sliding portion 413, and the first sliding portion 220 is slidably connected to the second sliding portion 413. The outer case 410 is slidable in a first direction with respect to the first coupling sleeve 200, and in a direction opposite to the first direction, by the engagement of the second sliding portion 413 with the first sliding portion 220. So as to lock or unlock the outer case 410 with an external device such as an adapter.
Preferably, the two housings 410 installed at both sides of the first coupling sleeve 200 are of a split structure. Fig. 3, 4, 7, 8 and 11 and 13 exemplarily show two outer casings 410 separated, the outer casings 410 having a substantially plate shape. The two housings 410, which are separated, are physically independent from each other, and the two housings 410 may have the same structure for convenience of manufacture.
Preferably, two outer cases 410 are installed at opposite sides of the first coupling sleeve 200, respectively. Taking the first connecting sleeve 200 with a square cross-sectional shape as an example, without limitation, as shown in fig. 3 to 5, two outer sleeves 410 are respectively installed on the upper and lower side surfaces of the first connecting sleeve 200, and a partial area on the peripheral side of the first connecting sleeve 200 is not connected with the outer sleeves 410, so that the width dimension of the assembly body in the second direction is reduced. In contrast to the prior art assembly of casing b and head receiving portion a of fig. 1, the reduced size of the assembly of the present embodiment is at least two thickness values of casing b.
Further, the width of the outer case 410 in the second direction is less than or equal to the width of the first coupling sleeve 200 in the second direction; the second direction is perpendicular to the first direction. As shown in fig. 3, the width of the outer case 410 in the second direction is equal to the width of the first coupling sleeve 200 in the second direction. Due to the arrangement, the situation that the width of the assembly body along the second direction is larger due to the fact that the outer sleeve 410 protrudes out of the first connecting sleeve 200 can be avoided.
In order to facilitate the resetting of the outer sleeve 410 in the push-pull moving process, the assembly body further includes a resetting member 420 corresponding to the outer sleeve 410 one by one, the resetting member 420 is located in the accommodating space formed by the outer sleeve 410 and the first connecting sleeve 200, and the resetting member 420 abuts against the outer sleeve 410 to provide an elastic force to the outer sleeve 410.
The restoring member 420 may be a spring, a spring plate, a part or a mechanism capable of providing elasticity. Specifically, as shown in fig. 4, 7 and 8, the restoring member 420 is a spring. The restoring member 420 provides an elastic force to the outer case 410 along its axis.
In some embodiments of the present invention, the housing 410 is provided with a placement hole 411 communicating with the accommodation space, and the reset member 420 enters the accommodation space through the placement hole 411. When the first connecting sleeve 200, the outer sleeve 410 and the reset piece 420 are assembled, the outer sleeve 410 can be firstly installed on the first connecting sleeve 200, and then the reset piece 420 is installed through the placing hole 411; the reset piece 420 can be installed on the first connecting sleeve 200 firstly, and then the outer sleeve 410 is installed, so that the assembling sequence is reduced, and the professional requirement on field installation is reduced. The assembly body can be pre-installed, and the convenience of transportation and field installation is improved.
Further, the outer casing 410 includes two second sliding portions 413, the first connecting casing 200 includes two first sliding portions 220, the two second sliding portions 413 and the two first sliding portions 220 are both disposed at intervals along the first direction, the accommodating space includes an interval space 224 between the two first sliding portions 220, and the reset piece 420 is located in the interval space 224.
Further, one end of the reset member 420 abuts against one of the second sliding portions 413, and the other end of the reset member 420 abuts against one of the first sliding portions 220. On the basis of fig. 4, when an external force is applied to the housing 410 to move the housing 410 in a direction opposite to the first direction, the second sliding portion 413 located at the front of the housing 410 compresses the reset member 420, the housing 410 is separated from the external device such as an adapter or a device to perform unlocking, and after the external force is removed, the housing 410 is restored to the original position by the elastic restoring force of the reset member 420 so as to be locked next time.
In some embodiments of the present invention, each of the second sliding portions 413 includes at least two protrusions 412, a stopper portion 414, and a track groove 415 between two adjacent protrusions 412; the first sliding portion 220 slides along the rail groove 415; the stopper portion 414 is provided on the projection portion 412; one of the stopper portions 414 abuts against the first slide portion 220. When the assembly is provided with the reset member 420, the stopper portion 414 abuts against the reset member 420 at the same time.
The stopper 414 of each second sliding portion 413 may have the same structure. As shown in fig. 5 and 6, the structure of the stop portion 414 of each second sliding portion 413 may be different. Here, the stopper portion 414 of the second sliding portion 413 located at the front end can seal the rear end opening of the rail groove 415, and here, the rear end face 4141 of the stopper portion 414 abuts on the reset member 420, and the front end face 4142 abuts on the second sliding portion 413. The stopper 414 of the second sliding portion 413 at the rear end does not affect the openings at both ends of the rail groove 415, and is only used to abut against the first coupling sleeve 200 to limit the forward displacement of the outer sleeve 410. The stopper 414 improves the accuracy of the fit between the outer case 410 and the first joint housing 200.
The first sliding portion 220 includes a slider 222, and the slider 222 slides in the track groove 415. When the assembly body is provided with the reset piece 420, the slider 222 abuts against the reset piece 420. It is understood that the number of sliders 222 depends on the number of the protrusion 413, and if the number of the protrusion 413 is n, the number of sliders 222 is n-1, and n is a positive integer.
Without limitation, each first sliding portion 220 further includes a protrusion 221 respectively located at both sides of the slider 222. As shown in fig. 5 to 7, when the second sliding portion 413 includes two protruding portions 412, the first sliding portion 220 includes one slider 222, the slider 222 slides in the track groove 415, and the reset member 420 can abut against the slider 222 of the second sliding portion 413 located at the rear end.
Further, the side wall 223 of the slider 222 has a stopper 2231 protruding outward. As shown in fig. 5, the upper portion of the side wall 223 of the slider 222 is inclined away from the protrusion 221, the lower portion of the side wall 223 of the slider 222 is inclined toward the protrusion 221, and the middle portion of the side wall 223 has a stopper 2231. In addition, the side wall 223 of the slider 222 may be a slope inclined toward the bump 221, that is, a space with a small top and a large bottom is formed between the slider 222 and the bump 221, and in this case, the stopper 2231 may be located at an upper portion of the side wall 223.
The engagement between the position-limiting portion 2231 and the track groove 415 effectively prevents the outer case 410 from being separated from the first coupling sleeve 200 in the vertical direction, thereby improving the assembling stability of the second sliding portion 413 and the first sliding portion 220.
Further, the protrusion 412 is accommodated in the space between the slider 222 and the protrusion 221, and the protrusion 221 located on both sides further increases the limiting effect on the second sliding portion 413, so as to further improve the firmness of the assembly of the outer sleeve 410 and the first connecting sleeve 200.
The embodiment of the present invention further provides a connector, wherein the connector 600 includes the second connection sleeve 100, the elastic device 300, and any one of the above-mentioned assemblies; the second connecting sleeve 100 is installed on the first connecting sleeve 200, one end of the elastic device 300 is abutted against the ferrule 11 located in the first connecting sleeve 200, the other end of the elastic device 300 is abutted against the second connecting sleeve 100, and the elastic device 300 provides a pretightening force to the ferrule 11.
As shown in fig. 3, 7 and 8, the second connection sleeve 100 is located at the rear end of the first connection sleeve 200, and the second connection sleeve 100 can almost completely extend into the second connection sleeve 100, so that the space occupied by the connector 600 can be minimized. The elastic means 300 is located in the space formed by the first coupling sleeve 200 and the second coupling sleeve 100, and thus, the width of the assembly body determines the width of the connector 600. As can be seen from the above embodiments, the size of the connector 600 is also reduced by providing the outer cases 410 on both sides of the first coupling sleeve 200, respectively.
As shown in fig. 11 and 12, the size of the connector 600 of the embodiment of the present invention is smaller than that of the prior art adapter using the same adapter. Specifically, the width D1 of the connector 600 according to the embodiment of the present invention in the second direction is 4.2cm, while the width D2 of the connector D according to the prior art is 7.7cm, on the premise that the connector D according to the prior art is identical to the connector 600 according to the embodiment of the present invention except that the housing has a cylindrical structure with both ends open. Accordingly, the corresponding size of the adapter to which the connector 600 of the present invention is connected may be reduced relative to the adapter shown in fig. 11 and 12.
As shown in fig. 13, with the connector 600 of the embodiment of the present invention, more sockets can be provided on the device e in the same area region f to connect more connectors 600.
The elastic device 300 can provide a pre-tightening force to the ferrule 11 along the axis (also referred to as the axis O in fig. 9) to ensure the coupling effect of the ferrule 11. The elastic means 300 may be a spring, a leaf spring, a part or a mechanism capable of providing elasticity.

As shown in fig. 8 to 10, the first notch 310 penetrates through the side of the elastic device 300, and the second notch 110 penetrates through the sidewall of the second connection sleeve 100. The projection of the elastic means 300 along its axis O has a substantially C-shape. The optical fiber 12 can enter the elastic device 300 through the first notch 310 and enter the first connecting sleeve 200 through the second notch 110, and the ferrule 11 is not required to be removed in the after-loading mode, so that the connector 600 can be assembled under the condition that the original connection relation between the optical fiber 12 and the ferrule 11 is not changed, the waste of materials is avoided, the assembly efficiency of the connector 600 is improved, and the construction period is shortened.
As shown in fig. 4, the first coupling sleeve 200 includes a first hole 230 and a second hole 240 arranged in parallel with the first hole 230 in the axial direction of the first hole 230, a step surface 250 is formed between the first hole 230 and the second hole 240, and when the ferrule 11 enters the first hole 230 from the second hole 240, the step surface 13 of the ferrule 11 abuts against the step surface 250.
In some embodiments of the present invention, the second connection sleeve 100 further includes a first stop surface 141 disposed adjacent to the ferrule 11, the elastic device 300 is located between the ferrule 11 and the first stop surface 141, and the elastic device 300 abuts against the first stop surface 141.
Referring to fig. 7, the ferrule 11 enters the first coupling sleeve 200 from the second bore 240 at the rear end, wherein the head of the ferrule 11 can enter the first bore 230 and the tail is located in the second bore 240 due to the abutment of the step surface 13 of the ferrule 11 with the step surface 250. Under the pre-tightening force of the elastic device 300, the step surface 13 of the ferrule 11 is always abutted against the step surface 250 in the first connecting sleeve 200.
The elastic means 300 may directly abut against the ferrule 11, or the elastic means 300 may be indirectly connected to the ferrule 11. As shown in fig. 8, the connector 600 further includes a key block 500, the key block 500 is located between the ferrule 11 and the elastic means 300, and the elastic means 300 abuts against the key block 500.
Further, the second connecting sleeve 100 is connected with the first connecting sleeve 200 in a clamping manner, and after the second connecting sleeve 100 is connected with the first connecting sleeve 200, the second connecting sleeve 100 and the first connecting sleeve cannot move relatively. The elastic means 300 is compressed in the space formed by the second coupling sleeve 100 and the first coupling sleeve 200,
